Percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign (%). A percentage is a dimensionless number, primarily used for expressing proportions, but percent is nonetheless a unit of measurement in its orthography and usage. In CSS, it is often used to define a size as relative to an element's parent element. For example, if parent element's size is 1000px, then 1% will be equal to 10px, 1% = 10px.
